Hi bro, 

Talking about clearing an year and being promoted for next year.. .out of 12 subjects in a year you have to atleast pass in 60 subjects.. ie 40 marks out of 100 in 6 subjects out of 12...And even if you get 36 marks out of 100 IP will give you 4 extra marks as a grace.. So according to me it's almost impossible to get an year back in IP university.. 

Thanks
